Completing Interstate 22 in Alabama has been a multi-year project that wrapped up in 2015 when the $168 million initiative opened for business across a 213-mile-long stretch between Memphis, Tenn., and Birmingham, Ala.

When the Alabama Department of Transportation (ALDOT) decided to replace the 84-year-old B.B. Comer bridge over the Tennessee River, it knew that the multi-year project was both a necessity and a monumental undertaking.
